Supplemental medical gas system

Abstract

A supplemental medical gas system and method utilizes a wheeled handcart, a reel disposed thereon having a length of the hose disposed thereon and extendable therefrom. Couplings are provided and disposed on opposite end of the hose for establishing connection with a gas supply and a hospital conduit system. In addition, at least one berm disposable on the handcart and deployable therefrom is provided for overlaying the extended hose for enabling the vehicular travel thereacross.

1. A method for transferring medical gas from a remote stationary bulk supply of gas to a spaced apart low pressure hospital medical gas conduit system during interruption of a permanent connection between the remote stationary supply and the conduit system, the method comprising:
 providing a wheeled cart with a rotatable reel for supporting a length of hose, said hose having a coupling fitting on each thereof; 
 connecting one end of the hose to the remote stationary bulk supply of gas via one of the coupling fittings the bulk supply of gas being separated from said wheeled cart; 
 unreeling the hose and extending the hose to the spaced apart conduit system; and 
 connecting another end of the hose to the conduit system via another of the coupling fittings, the conduit system being separated from said wheeled cart. 
 
     
     
       2. The method according to  claim 1  further comprising purging the hose with the gas prior to transfer of the gas from the supply to the conduit system. 
     
     
       3. The method according to  claim 1  further comprising disposing berms over the extended hose to enable vehicle traffic thereover. 
     
     
       4. A method according to  claim 3  further comprising controlling hose payout during hose unreeling via a reel brake.
